The Internet of Things (IoT) is a transformative technology, which is revolutionizing our
everyday life by connecting everyone and everything together. The massive number of …

Physical layer security is a promising approach that can benefit traditional encryption
methods. The idea of physical layer security is to take advantage of the propagation …

This paper proposes a new design of non-orthogonal multiple access (NOMA) under
secrecy considerations. We focus on a NOMA system, where a transmitter sends confidential …

A covert communication system under block fading channels is considered, where users
experience uncertainty about their channel knowledge. The transmitter seeks to hide the …

Covert communications enable a transmitter to send information reliably in the presence of
an adversary, who looks to detect whether the transmission took place or not. We consider …

With the gradual promotion of the fifth generation (5G) mobile communication and Internet of
Things (IoT) applications, wireless communication transmission will be more vulnerable to …

We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …

In this paper, we examine the physical layer security of a cooperative relay network where
two source-destination pairs communicate through a decode-and-forward (DF) relay in the …

We propose covert beamforming design frameworks for integrated radar sensing and
communication (IRSC) systems, where the radar can covertly communicate with legitimate …

In this paper, we propose a secure computationoffloading scheme (SCOS) in intelligently
connected vehicle (ICV) networks, aiming to minimize overall latency of computing via …
